In business, women leaders often have to work a little harder than their male counterparts to secure their seats at the boardroom table. Once they’ve earned that leadership position, things don’t get any easier.

If you watched the Democratic primary debate last night, one thing probably stood out to you, regardless of your political leanings: Hillary Clinton was the only woman on the stage. In fact, as far as American politics is concerned, one out of five is just about the norm: currently, women hold 104 out of 535 seats in Congress, a 19.4 percent average. (It gets worse if you look at women of color – 31.7 percent of the number of women, and just 6.2 percent of the total.) Of course, we love data, but numbers can seem abstract. Sometimes, you can't beat a good visualization to really see the problem. Recently, British Elle's feminism issue gave us just that, with a video that shows men gradually removed from photos of politics in action ... leaving just a few women behind.

Working women continue to be steadfast in their fight for gender equality in the workplace. And, it's paying off, especially for millennials, who now have the greatest support of any generation of women. Here are a few signs that it's time for millennial women to break the glass ceiling once and for all.

While some girls are busy dreaming about their wedding day, others are fantasizing about being the next Sheryl Sandberg or Mary Barra. For the ambitious, here's some advice to support you in your endeavors and encourage you to become the leader you are truly meant to be.

If you can't name the right number, don't worry: neither can executives. The 1,700 participants of a Weber Shandwick study guessed that 23 percent of CEOs at large companies were women. Take a look at the embarrassing results of the study and the shocking truth of how few female CEOs actually exist today.

The bad news is that STEM has a woman problem. The good news is that everyone is pretty aware of it now and some companies are trying to fix this problem. Last year, LinkedIn announced its Women in Tech (WIT) initiative, which aims to empower the women in tech roles at the company to transform themselves, their careers, and the company – and, by golly, it seems to be working! We'll take a look at how LinkedIn is "tackling this imbalance head-on" and making a difference for women in tech, now and in the future.

Who better to bring awareness to a vital cause like women's equality than Hollywood stars? We'll take a look at how some of Hollywood's most revered actresses are speaking out about the inequality women face on- and off-screen, and the role the media plays in perpetuating this unconscious bias.

Times change, and our understanding of the past changes right along with it. A great many things were different, say, 100 years ago, in America. For starters, women couldn't vote. In fact, the oppression -- marginalization is way too weak a word -- of women and minority groups was so abundant 100 years ago that there is hardly a comparison between their experience then and now. So, it makes sense that we see certain things a little differently today that we did in the past.

"Women make better CEOs." These fine words come from none other than Kevin O'Leary, better known as Mr. Wonderful on ABC's The Shark Tank. O'Leary holds an impressive business portfolio, and 55 percent of the CEOs in it are women. Why, then, are women so exceedingly underrepresented in high-level, leadership positions still to this day? One ongoing study examined just that.
